Application filed July 17,

My said invention relates to a dial aligning device such as is used in dial and cylin der knitting machines of the so-called dogless type, and it is an object of the same to provide a device of this character with means for obtaining a very accurate adjust ment of the dial needles with reference to the cylinder needles by simple mechanism capable of maintaining such adjustment indefinitely for the reason that the parts exposed to wear are so arranged and have such large bearing surfaces thatthe device can be used over a very long period of time without such wear as would afiect the ad justment and relative positions of the needles so as to necessitate re-adjustment'.

Another object of the invention is to provide means in connection with the dial aligning device for ready and accurate adjustconventional or preferred construction. A

ment'of the dial in a vertical sense.

Referring to the drawings, in which "similar reference characters indicate similar parts, and which drawings are made a part hereof: v Fig. 1 is an elevation of a part of a dial and cylinder knitting machine, with parts broken away for clearness of disclosure,

Fig. 9 an elevation of another modification, partly in section, I v

Fig. 10, a horizontal section on line l010 of Fig. 9, and

Fig. 11, a vertical section on line 1111 of Fig. 9. In the drawings, reference character 20 indicates a part of the fixed head ofa machine of the type in which the needle cylin der and the dial are stationary, though it will be obvious that my invention may be applied to a machine in which the cylinder and dial revolve while. the cam-carriers stand still, in'which case thepart 20 will be a corresponding element of such a machine; Posts 21 r1sefrom thehead and at their upper ends support a yoke 22 havlique bearing portion for an ob=- 1929; Serial No. 123,140

lique or inclined annular plate 23 held in position on the bearing'bya ring 24 recessed at its underside to provide a circumferential bearing and an upper bearing for the plate 23.

The rotary cam ring 25 carries posts 26, as usual, on which are mounted a yoke 27 and posts 28, the posts carrying a yoke 29. The yoke 29 supports a post 30 secured in place by setscrews 31, and a bobbin table 32 is fixed tothe post in similar manner, the table bearing arms33 provided with bobbin holders 34 for bobbinsfifi. The cam ring and dial' cams may be caused to rotate. together by some suchmeans as are shown-in the patent to Butz, 1,012,982, De-

oember'26, 1911. r

The needle cylinder 36, the dial 37 and the dial cam cap 38, are, or may be, of any shaped adjusting block 41. A nut 42 hav-' ing threaded engagement with the dial post rests on the ad]usting block and servesto positionthe dial vertically." p

.The sleeve-40'is bifurcated at its upper end as shown at 43 in Fig.3 andterminates in a head 44 (Fig.1). Screws 45 are located inthe forks of the sleeve and bear at their freeends against lateral extensions of the adjusting block, whereby it will readily be seen thatadjustment of the screws will turn the dial post and the dialabout a vertical axis, thus serving to position the dial needles accurately between the cylinder needles. The head has a central hub providinga bearing for a circular opening-in the'plate, and the top of the head provides a bearing for the under side of the plate; A cap 47 is fixed to the head by a screw 48 and said cap bears ontheupper face of the plate, all the'bearings so far described fitting the plate The post is flattened at or near its 1 closely so as to insure accurate maintenance through any suitable guides and down i through holes or passages 50 in the plate 23. I

It will be seen that as the cam ring revolves the plate is forced to move with it on iac-' scent of the pressure of the posts" 28 against parts supporting it and supported thereby,

thusalso acting in a very positive andunvarying manner -to prevent any angular movement of the dial and the parts supporting it. .j-

lathe form of the device illustrated in Eigs; 6-, and 8 the conventional parts are, or may ;be, as inthe form justdescrlbed.

The dial post 39 is, however,flattened at a pointapproximately midway of its length and the sleeve 40 is emitted. A- clevis-shaped clamping block, 53 fitsclosely-on the flattenedpart of the-dial postand is clamped in' Fig; I2qfor the accommodation of different;

for the work the machine is to perform.v At their outer periphery the plates are sup b ported: by a fioatingframe comprising a thereby a bolt 5 A nut 55 threaded on the dialpost rests on the block v53 and serves for adjustment of the dial post up or down. Abo've'thenut'a horizontal plate 56 has an easy turning fit on the post. Further up the ,post has. a shoulder'on whichsits a block57 iwithan inclined upper face'o'n.

which an inclined plate 581has its bearing. Another block 59 ;on the post. has a hub fitting closely inacentral opening'iin the plate 58, this block being locked against the .The a two plates noted'thatfour of these passages are shown yarns all as maybe, necessary or desirable main body portion62iandiremovable ends 63 and 6a heldin place by; screws or other means. ;At one side the body has extensions v-6 5 carrying opposedscrews 66 bearing againstopposite'sides of a.-post 67 on the head ;-of the machine. adjusting thescrews the position of the upper plate can" be varied toprovide accurate adjustment of the di l- ;and such adjustment wi be rigidly and permanentlylmaintained.as will be obvious, with the result that the dial needles may, beheld accurately and permanently in place relatively to the cylinder needles iiFig'sQ-Qflto 11 depict a highly desirable form "of my inventiomiin which the parts arejarra -nged and; supported in a manner to relieve the dial; of weight and twist in very effective manner, and so asto confine the -wea'r to points where it can do ,no harm.

' vention, what claim 68 is clamped to the dial post as in the form just described and bears a post 69. The floatbut is held rigidly'to a post 70 on the machine head by alink 71 connected at ing frame may be generally similar to that its otherrend to said floating frame. The

upper plate or disk 72 is fixed to the posts 73,. said plateresting on shoulders on the posts and beingclamped in place by nuts on the threaded upper ends of the posts. The

frame is thus supported by the upper disk,

beingheld against rotationby the link 71. and the lower inclined disk 72 is rotatably supported by theframe, Each disk has as many yarn passages asmay be desirable and the lower diskhas openings for the posts 7 3 which openings may be provided with abutments as in Fignl as will be obvious. 1 i

, A bobbin table shaft 74: extends mmgth elongated hub-0f the plate 7 2 and issecured thereto by set screws 75. Below said shaft in said hub there: is a dial shaft?! which extendsthroughblocks 76 and 7 7 said blocks being clamped to:the dial shaft between shoulder on the shaft and anut atthe lower I end of the same, The Idial shaft may thus standstill while the, disk 7 2- rotates or may rotate while the diskstands still as the case" may be. The blocks 76 and 77 provide bearings for ,the lower inclined diskxinsimilar manner to Lthe} structures previously. de-' scribed andNare-provided.with screws 78, 7 8

for positioning the dialneedles relatiyely to the cylinderneedles, as in the form first dei scribedn 56 and 58 are" provided with openings to receive the posts 61 of the bobbin supportingmeans and with yarn pas-. sagesjof suitable size and number it being AS illustrated, the uts 56in m 6 as havea limited clearance at its outerfperiph cry to permit a certain amount of side play, and-the same is true of, theinn er peripheral bearing of plate 72 in Fig. 9, but the other plates shouldfit accurately at; all surfaces to insure correct/resultsj As previously stated, it will be obvious to those skilled in theart how to adapt the device, of i my invention for. use in machines having revolving needle cylinders. Numerous modifications and adaptations. of details bearing of the device will also occur to those who understand: the invention and the principles onwhich it is based, and thereforeI do not limit myself to the specific devices shown in the drawings and described in the specification, b ut only as indicated in the appended claims,

H aving fullydescribed my saidpin I and desire to secure by Letters Patent is;
